The path integral approach has proved useful for the understanding of the complex problems in quantum field theory, cosmology, and condensed matter physics. This book covers the fundamentals of path integrals, both the Wiener and Feynman types, and their many applications in physics.

Presents the fundamentals of path integrals, both the Wiener and Feynman type, and their many applications in physics. This book deals with systems possessing a infinite number of degrees in freedom. It discusses the general physical background and concepts of the path integral approach used.

Presents an exposition of the role of symmetry, particularly rotational symmetry, in quantum mechanics. This book covers the description of rotations (geometrically and group-theoretically) and their representations, and the quantum theory of angular momentum. It introduces advanced topics such as relativistic theory, supersymmetry, and anyons.
